A specific touch movement will cause the home button to appear on the screen. It will then act much like the current & new-patent designs.The 7 Home button is the equivalent of power-steering for a car—we all still see a steering wheel. Explain how a no home button design plays out on the display. I'm using Notes, how do I get to the Home screen? Explain it in a detailed manner. "A virtual Home button" is not a detailed explanation btw. How is it used?
(I wasn't sure whether you were questioning how it would be detected by the user or how the control itself would work. Obviously I've only addressed the former.)
